iNKlNG APPARATUS FOR PRlNTiNG MAGl-HNES.

:ZBPEQEFICATION forming part of Letters Patent No. 330,278, dated November 10, 1885.

Application filed January 8, 1885. Serial No. 152,289. (No model.) Patented in England February 22, 1884, No, 3,749.

To a whom it may concern:

Be it known that I, GEORGE ASHLEY WIL- sorr, the above-named petitioner, a subject of the Queen of Great Britain, residing at Broad Green, near Liverpool, in the county of Ian caster, England, have invented a new and use ful Inking Apparatus for Printing-Machines, (for which I have obtained a patent in Great Britain, No. 3, 749, bearing date February 22,

I0 1884, and nowhere else,) of which the following is a specification.

The invention relates to printing-machines in which type or stereotype and impression cylinders are used; and the object of my invention is so to construct inking apparatus that the type or stereotype shall be evenly and uniformly coated with ink in such manner that the higlrclass printing required for illustrated papers and books may be more perfectly effected on rotary cylinder printingmachines.

In the accompanying two sheets of drawings, Figure 1 is a side elevation, and Fig. 2 a plan, of the whole of the inking apparatus. Fig. 3

is a diagram showing the ductor-cylinder, 0s-

eillating take-off or feed-roller, dividing-roller, and distributingroller. Fig. 4 is alongitudi nal section, and Fig. 5 a plan, of the fountaincylinder and driving-gear.

In the drawings, 1 denotes the frame of printingpress; 2, frame secured to 1 and carrying theinking apparatus; 3, ink-trough; 4, fountaim-cylinder made withdepressions 5. The said fountain-cylinder is carried by and is free 5 to slide endwise on the shaft 6, but is prevented from turning thereon by the keys 7. The shaft 6 is carried in bearings in frame 2, and receives motion through the toothed wheel 8. 9 is a hand wheel attached to shaft 6; 10,

4o ductor-blade secured to the rocking bar 11 and adjusted in position by the set-screws 12; 13, lever hand-wheel and screw for giving motion to the rocking bar 11, so as to move the ductorblade to and from the fountain-cylinder in the usual manner; 14, cams attached to the ends of the fountain-cylinder; 15, rollers carried by bearing pieces 16, connected to the frame 2 by adjustingscrews 17 18, take-off or feed roller carried in eccentric bearings on the adjustable 5o arms 19, attached to the frame 2; 20, small roller carried by the bell-crank pivoted to the frame 2 at 22; 23, springs attached to one end of the bell-crank arms 21 and to the frame 2 for the purpose of keeping the roller 20 in contact wit-h the take-off roller 18; 24 25 26, metal rollers, two of which, 5 4 and 25, have endwise reciprocating motion imparted to them by the rocking shaft 27, which is actuated by the cam 28 and takes into the grooves 29 between the collars 30 on the shafts 31 of the rollers 24 and 25 32, toothed wheels which give rotary motion to the rollers 24 25 26 and the cylinder 4. 33, 34, 35, and 36 are composition rollers running in contact with the rollers 24, 25, and26; 37, inkingrollers; 38, riders; 39, type'or stereotype cylinder; 40, impression or blanket cylinder.

The operation of the apparatus is asfollows: The cylinder 4 takes ink from the trough 3 and carries it forward to the take-off or feed roller 18, any excess of or thick portions of ink being removed by the ductor-blade 10 and allowed to fall into the depressions 5 on the fountain-cylinder and thence into the inktrough 3. By means of the toothed wheel and cam above described the fountain-cylinder receives both a rotating and endwise motion, which causes the ink, which would otherwise be delivered to the take-off or feed. roller in parallel streaks, owing to the blade being closer to the fountaineylinder where the set-screws 12 bear on it, to be delivered thereto in diamond pattern. At the same time the small roller 20 spreads the diamond longitudinal patches of ink on the take-oft roller 18 twice or oftener, according to its size, before they reach the first distributing-roller, 24. From 24 the ink passes by aid of the composition rollers to the second distributingroller, 25, and thence to the final roller, 26. From roller 26 0 the ink is delivered to the composition inkingrollers 37,- riders 38, and type or stereotype cylinder 39.

I am aware that a fountaiirroller grooved with small shallow grooves is not new, and I 5 do not desire to claim the same.

I claim- 1. In inking apparatus for I rotary webprinting machines, the combination, with a fountain-cylinder, of toothed wheel and cam Ioo to impart rotary and reciprocating motion thereto. 7

2. In the inking apparatus of rotary Webprinting machines, the fountain cylinder hav- 5 ing recesses formed in the face thereof, substantia11y as and for the purpose specified.

3. In the inking apparatus of rotary webprinting machines, the combination of afountain-cylinder, a takeofi' roller,- a small spreading-roller bearing on the take-off roller, and a IO pivoted spring-lever for retaining the spreading-roller in contact with the takeofi roller, substantially as and for the purposes described.
